Description

Technical Field

[0001] This application relates to the field of graphite digestion apparatus technology, and more particularly to a graphite digestion apparatus. Background Technology

[0002] A graphite digestion apparatus is an analytical instrument used in the fields of chemistry, agronomy, forestry, environmental science and technology, and resource science and technology. It is commonly used for the digestion of samples such as soil, food, fertilizer, and rocks.

[0003] The graphite digester uses graphite blocks to generate high temperatures to digest samples placed in digestion tubes. Users can customize the required temperature, and the instrument will automatically and uniformly raise the temperature to the specified temperature and then maintain the temperature to continuously heat the sample.

[0004] When using existing graphite digestion instruments, the digestion tube is directly inserted into the corresponding socket, and then heated by the graphite digestion instrument. However, during use, since only part of the digestion tube is inside the socket and the other part is outside the graphite digestion instrument, uneven heating is likely to occur when heating the digestion tube with the existing graphite digestion instrument, which is not conducive to the decomposition of the sample.

[0005] Therefore, this application proposes a graphite digestion apparatus. Utility Model Content

[0006] This application proposes a graphite digestion apparatus to address the problems mentioned in the background section. The apparatus features a heating chamber with a sliding support frame inside. A locking door seals the heating chamber, and the graphite heating zone is located within it. During use, the support frame is first removed to allow the operator to insert the digestion tube into the corresponding insertion hole. The support frame is then slid back into the heating chamber, and the locking door is closed. The sealed heating chamber provides a stable heating environment for the digestion tube. After heating, the support frame is removed entirely for heat dissipation or for the operator to retrieve and replace the digestion tube. Because the support frame is completely within the heating chamber while the digestion tube is inserted, uneven heating is avoided, promoting sample decomposition, improving decomposition quality, and significantly enhancing the apparatus's practicality.

[0007] To achieve the above objectives, this application adopts the following technical solution:

[0008] A graphite digestion apparatus includes a digestion apparatus body. The digestion apparatus body has a heating chamber and a graphite heating zone inside. The graphite heating zone is located inside the heating chamber. A support frame is located inside the heating chamber and is situated within the graphite heating zone. The support frame has several insertion holes inside. A latching door is rotatably connected to the front end of the digestion apparatus body via a rotating rod. A control panel is fixedly connected to the top of the digestion apparatus body.

[0009] In a preferred embodiment, the digester body is provided with a moving mechanism, which includes a motor, a main gear, a driven gear, a rotating shaft, a pinion, and a toothed groove.

[0010] By setting up a moving mechanism, the entire support frame can be moved out to facilitate heat dissipation or allow experimenters to access and replace new digestion tubes. By inserting the digestion tube into the insertion hole, the support frame is completely located within the heating chamber, thus preventing uneven heating, which is beneficial for sample decomposition, improves decomposition quality and grade, and enhances the practicality of the device.

[0011] In a preferred embodiment, the rotating shaft is rotatably connected to the inner bottom of the digester body, and two small gears are fixedly connected to the outside of the rotating shaft. Two toothed grooves are opened at the inner bottom of the support frame, and the two small gears are respectively meshed with the corresponding toothed grooves.

[0012] When the shaft rotates, it drives two small gears to rotate synchronously. The small gears mesh with the tooth grooves, causing the support frame to move within the heating chamber, thereby improving the practicality of the device.

[0013] In a preferred embodiment, a motor is fixedly connected to the bottom of the digester body, a main gear is fixedly connected to the top output end of the motor, a driven gear is fixedly connected to one end of the rotating shaft, and the main gear and the driven gear are meshed together.

[0014] The motor is driven by the control panel. The motor drives the main gear to rotate. The main gear meshes with the driven gear to make the shaft rotate. When the shaft rotates, it drives the two small gears to rotate synchronously, thereby improving the practicality of the device.

[0015] In a preferred embodiment, the support frame is provided with a sliding mechanism, which includes a limiting slider and a limiting groove;

[0016] By setting up a sliding mechanism, the sample in the decomposition tube is prevented from being affected by factors such as shaking, tilting, and instability during the movement of the support frame, thereby improving the practicality of the device.

[0017] In a preferred embodiment, the limiting slider is fixedly connected to the heating chamber of the digester body, and a limiting groove is formed at the bottom of the inner side of the support frame between two toothed grooves, and the support frame is slidably connected to the limiting slider through the limiting groove.

[0018] By setting up a sliding mechanism, when the support frame moves, it will slide synchronously on the limit slider through the opened limit slide groove, which improves the stability of the support frame during movement and thus enhances the practicality of the device.

[0019] In a preferred embodiment, a telescopic mechanism is provided on one side of the digester body, the telescopic mechanism including an electric push rod, a fixed block, a movable block and a mounting block;

[0020] The electric push rod is driven by the control panel. The telescopic end of the electric push rod moves the fixed block away from the digester body. The movable block rotates downward inside the fixed block, causing the mounting block to drive the latching door to rotate away from the heating chamber via the rotating rod, thus opening the latching door and improving the practicality of the device.

[0021] In a preferred embodiment, the electric push rod is fixedly connected to the inside side of the digester body, the telescopic end of the electric push rod extends to the outside of the digester body and is fixedly connected to a fixed block, the mounting block is fixedly connected to the outside of the latching door, the side of the mounting block away from the latching door is fixedly connected to a movable block, and the end of the movable block away from the mounting block is rotatably connected to the inside of the fixed block.

[0022] By driving the electric push rod again, the telescopic end of the electric push rod drives the fixed block to move towards the digester body. Under the action of force, the movable block rotates upward within the fixed block, causing the mounting block to drive the latching door to rotate towards the heating chamber via the rotating rod to close the latching door. The sealed heating chamber provides a stable heating environment for the digestion tube, thereby improving the practicality of the device.

[0023] The beneficial effects of this application are:

[0024] 1. This graphite digestion apparatus features a heating chamber with a sliding support frame inside. A locking door seals the heating chamber, and the graphite heating zone is located within it. During use, the support frame is first removed to allow the operator to insert the digestion tube into the corresponding insertion hole. The support frame is then slid back into the heating chamber, and the locking door is closed. The sealed heating chamber provides a stable heating environment for the digestion tube. After heating, the support frame is removed entirely for heat dissipation or for the operator to retrieve and replace the digestion tube. Because the support frame is completely within the heating chamber while the digestion tube is inserted, uneven heating is avoided, promoting sample decomposition, improving decomposition quality and efficacy, and significantly enhancing the practicality of the apparatus.

[0025] 2. This graphite digestion apparatus, by setting a sliding mechanism, allows the support frame to slide synchronously on the limiting slider through the opened limiting groove when the support frame moves, thereby improving the stability of the support frame during movement and avoiding the impact of shaking, tilting, instability and other factors on the sample in the digestion tube during the movement of the support frame, thus greatly improving the practicality of the device.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0031] Reference Figure 1-3 A graphite digestion apparatus includes a digestion apparatus body 1. The digestion apparatus body 1 has a heating chamber 11 and a graphite heating zone 12 inside. The graphite heating zone 12 is located inside the heating chamber 11. A support frame 2 is located inside the heating chamber 11 and is located inside the graphite heating zone 12. The support frame 2 has several insertion holes 21 inside. The front end of the digestion apparatus body 1 is rotatably connected to a latching door 4 via a rotating rod 41. A control panel 3 is fixedly connected to the top of the digestion apparatus body 1.

[0032] The digester body 1 is equipped with a moving mechanism 6, which includes a motor 61, a main gear 62, a driven gear 63, a rotating shaft 64, a pinion 65, and a toothed groove 66. By setting up the moving mechanism 6, the support frame 2 can be moved out as a whole to facilitate heat dissipation or to allow the experimenter to take it out and replace the new digestion tube. By inserting the digestion tube into the insertion hole 21, the support frame 2 is completely located in the heating chamber 11, so there will be no uneven heating, which is conducive to the decomposition of the sample, improves the decomposition quality and grade, and thus enhances the practicality of the device.

[0033] The rotating shaft 64 is rotatably connected to the bottom of the digester body 1. Two small gears 65 are fixedly connected to the outside of the rotating shaft 64. Two toothed grooves 66 are opened at the bottom of the inside of the support frame 2, and the two small gears 65 are respectively meshed with the corresponding toothed grooves 66. When the rotating shaft 64 rotates, it will drive the two small gears 65 to rotate synchronously. The small gears 65 mesh with the toothed grooves 66, causing the support frame 2 to move in the heating chamber 11, thereby improving the practicality of the device.

[0034] A motor 61 is fixedly connected to the bottom of the digester body 1. A main gear 62 is fixedly connected to the top output end of the motor 61. A driven gear 63 is fixedly connected to one end of the rotating shaft 64, and the main gear 62 and the driven gear 63 are meshed together. The motor 61 is driven by the control panel 3. The motor 61 drives the main gear 62 to rotate. The meshing of the main gear 62 and the driven gear 63 causes the rotating shaft 64 to rotate. When the rotating shaft 64 rotates, it will drive the two small gears 65 to rotate synchronously, thereby improving the practicality of the device.

[0035] The support frame 2 is equipped with a sliding mechanism 7, which includes a limiting slider 71 and a limiting groove 72. By setting up the sliding mechanism 7, the sample in the decomposition tube is prevented from being affected by factors such as shaking, tilting, and instability during the movement of the support frame 2, thereby improving the practicality of the device.

[0036] The limiting slider 71 is fixedly connected to the heating chamber 11 of the digester body 1. The bottom of the support frame 2 is provided with a limiting groove 72 between the two toothed grooves 66, and the support frame 2 is slidably connected to the limiting slider 71 through the limiting groove 72. By setting the sliding mechanism 7, when the support frame 2 moves, the support frame 2 will slide synchronously on the limiting slider 71 through the limiting groove 72, which improves the stability of the support frame 2 during movement and thus enhances the practicality of the device.

[0037] A telescopic mechanism 5 is provided on one side of the digester body 1. The telescopic mechanism 5 includes an electric push rod 51, a fixed block 52, a movable block 53, and a mounting block 54. The electric push rod 51 is driven by the control panel 3. The telescopic end of the electric push rod 51 drives the fixed block 52 to move away from the digester body 1. The movable block 53 rotates downward within the fixed block 52, causing the mounting block 54 to drive the latching door 4 to rotate away from the heating chamber 11 via the rotating rod 41 to open the latching door 4, thereby improving the practicality of the device.

[0038] An electric push rod 51 is fixedly connected to the inside of the digester body 1. The telescopic end of the electric push rod 51 extends to the outside of the digester body 1 and is fixedly connected to a fixed block 52. An mounting block 54 is fixedly connected to the outside of the latching door 4. A movable block 53 is fixedly connected to the side of the mounting block 54 away from the latching door 4, and the end of the movable block 53 away from the mounting block 54 is rotatably connected to the inside of the fixed block 52. By driving the electric push rod 51 again, the telescopic end of the electric push rod 51 drives the fixed block 52 to move towards the digester body 1. Under the action of force, the movable block 53 rotates upward within the fixed block 52, causing the mounting block 54 to drive the latching door 4 to rotate towards the heating chamber 11 via the rotating rod 41 to close the latching door 4. The sealed heating chamber 11 provides a stable heating environment for the digestion tube, thereby improving the practicality of the device.

[0039] Working principle: A heating chamber 11 is provided on the digester body 1. A support frame 2 is slidably installed in the heating chamber 11. A locking door 4 is provided on the digester body 1 to seal the heating chamber 11. The graphite heating zone 12 of the digester body 1 is located in the heating chamber 11. In use, the electric push rod 51 is driven by the control panel 3. The telescopic end of the electric push rod 51 drives the fixed block 52 to move away from the digester body 1. The movable block 53 rotates downward in the fixed block 52, causing the mounting block 54 to engage. Door 4 is opened by rotating the lever 41 away from the heating chamber 11. Then, the control panel 3 drives the motor 61, which in turn drives the main gear 62 to rotate. The main gear 62 meshes with the driven gear 63, causing the rotating shaft 64 to rotate. When the rotating shaft 64 rotates, it drives the two small gears 65 to rotate synchronously. The small gears 65 mesh with the tooth grooves 66, causing the support frame 2 to move away from the heating chamber 11. This removes the support frame 2, making it easier for the operator to insert the digestion tube into the corresponding insertion hole 21. Then... The drive motor 61 drives the main gear 62 to rotate. The main gear 62 meshes with the driven gear 63, causing the rotating shaft 64 to rotate. When the rotating shaft 64 rotates, it drives the two small gears 65 to rotate synchronously. The small gears 65 mesh with the tooth grooves 66, causing the support frame 2 to move towards the heating chamber 11. The support frame 2 is moved and slid into the heating chamber, and the electric push rod 51 is driven again. The telescopic end of the electric push rod 51 drives the fixed block 52 to move towards the digester body 1. Under the action of force, the movable block 53 moves against the fixed block. Rotating upwards within 52 causes the mounting block 54 to drive the latching door 4 to rotate towards the heating chamber 11 via the rotating rod 41, closing the latching door 4. The sealed heating chamber 11 provides a stable heating environment for the digestion tube. After heating is complete, the support frame 2 is moved out as a whole to facilitate heat dissipation or to allow the experimenter to take and replace the new digestion tube. By inserting the digestion tube into the insertion hole 21, the support frame 2 is completely located within the heating chamber 11, thus preventing uneven heating, which is beneficial for sample decomposition and improves the decomposition quality and grade.

[0040] By setting up the sliding mechanism 7, when the support frame 2 moves, the support frame 2 will slide synchronously on the limiting slider 71 through the opening limiting slide groove 72, thereby improving the stability of the support frame 2 during movement and avoiding the sample in the decomposition tube from being affected by factors such as shaking, tilting, and instability during the movement of the support frame 2.

[0041] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and the inventive concept of this application, should be included within the scope of protection of this application.
